javascript oop tutorial

Javascript is a function language that is too flexible, and its language mechanism is not provided completely. The entire object-oriented implementation (without the concepts of classes and inheritance), but with its flexible syntax However, oop can be implemented to a certain extent. For example, you can use the following syntax to implement the class Testa:Testa = function (nvalue ){This. m_nvalue = nval

Pseudo-class DeclarationOriginal address: Http://javascript.info/tutorial/pseudo-classical-pattern#pseudo-class-declarationA Pseudo-class consists of the constructor function and methods.For example, here's the Pseudo-class with single method and both Animal sit properties.function Animal (name) { THIS.name = Name}animal.prototype = { canwalk:true, sit:function () { This.canwalk = False alert (THIS.name + ' sits down. ') }} var animal = new

return New F ();}He is an encapsulation of class inheritance, in fact, the transition object is equivalent to the subclass in the class inheritance, but in the prototype as a transitional object appears, in order to create to return the new instantiated object.Of course, if you feel the need to cache the F transition, you don't have to create a new transition class F each time, and then the Object.create () method appears.varBook ={name:' JS book ', Alikebook: [' CSS book ', ' HTML book '],};va

class member, which is closely related to a class. Prototype also has an important property: constructor, which represents a reference to the constructor.　　Third, optimize the design pattern of JavaScript classImplements a member definition of a class by using the constructor of an untyped object to specify the prototype object:　　Iv. Common members, private members, and static members in JSPrivate members can share members in the internal implementat

Analysis of JavaScript OOP functions, javascriptoopAccording to Brandon Eich, the founder of JavaScript, the best language structure of JavaScript is: In my opinion, the most brilliant idea of JS is to break throughOOPThe limitation of the object, rather than the class, has become a first-class citizen (Eich's and 5 ar

FirstFirst, define a class using the keyword function function Shape1 (ax,ay) {// The function is considered to be the flag of the declaring class var x=0 ; var y=0 ; var init=function () {// The constructor assigns a value to the internal variable x=AX; Y =ay; }init (); // constructor call this . Getx=function () {// this declaration public Function Var declaration private get method return X; }}Then, the instantiation of the object + callvar shape=New Shape1 (1,2);

Before you learn JavaScript object-oriented programming, you need to know and understand some of the basic common sense of object-oriented. Most of the beginners think that object-oriented programming is very important and takes up a great part of the effort. I have previously thought that OOP is the main object-oriented part, then I hold the same idea, the following first to correct this idea, really under

prototype methods are added to the sub-class.Instance1.colors.push (' black '); Console.log (instance1.colors); // [' Red ', ' blue ', ' green ', ' black '] // [' Red ', ' blue ', ' green ']instance1.getname (); // CSSbook instance2.gettime (); // -Note: A subclass that wants to add a prototype method must pass a prototype object, one way to add it through the form of a point syntax, or it will be directly assigned to an object that overrides the inherited object from the parent class p

A practical reference to JavaScript oop editing ideas

According to JavaScript founder Brandon Eich, the best language constructs for JavaScript are: function is first class citizen (first functions) Closures (closure) Prototypes OBJ = {p1:1, P2: ' ABC '} Array = [+ +] I think that JS's most brilliant idea is to break through the limitations of OOP at that time, to turn object instead of

" can be used to better reflect real-world problems. On the other hand, the code contains some logic that describes the business, the business is comprised of business knowledge, and the business knowledge is summed up by the understanding and analysis of the real world, which is made up of "objects" in the real world. Objects contain features and behavior, in OOP terms, features are attributes of objects, and behavior is the object's method. Class

Hello readers, today we will proceed to the previous content, we have already talked about the inheritance, today we say that OOP is the last embodiment, that is polymorphic, because JavaScript language flexibility, so we have no way to use the interface, So this also brought a certain confusion to JS program, we do not have to worry too much about this problem, because these to the back of the ECMAScript l

Conversely, the code contains some logic, which is used to describe the business, the business is to contain some business knowledge, the business knowledge is through the understanding of the real world and analysis summed up, these problems are the real world "objects" constitute. objects contain features and behaviors, and in OOP terms, features are properties of objects, and behaviors are methods of
